I would want to showcase the highs and the lows.
Breakfast at Garden Grill; I consider this the best and most consistent AYCTE or buffet with fantastic character interaction. I recommend to everyone hoping it doesn't go away due to lack of interest but getting an ADR here isn't even needed at this point unless you want to get into the park early.
Coral Reef; Since we are in Epcot, let these executives see just how bad the food and service here is. Even if the staff knows the big bosses are coming I doubt they could pull off an acceptable meal.
Starring Rolls; let them see that a snack can be good without putting ears on it and covering it with too many flavors and pretty makeup. Carrot cake cookies for everyone

.
Hoop Dee Do; There isn't a better example of Disney quality, even over it's decades long run. To make it better they could rest on it being a good show and serve crappy food, yet the fried chicken is often named as some of the best WDW has to offer.
